Question you may concern
How do you know if the perpendicularity between the ground gear plane and the bearing hole has changed?
It can only be found when assembling the gear pump, because the end face clearance is very small, generally around 0.05mm. If the perpendicularity between the end face and the bearing hole has changed, the gear shaft cannot move after the pump is assembled. If the locking screw is loosened a little, but it still does not turn smoothly, and the gear pump is disassembled and inspected, there are scratches on the end face. This is caused by the end face plane not being perpendicular to the bearing hole.
